This is just what happens when hexamethylenediamine meets adipic acid forming another branded polymer, nylon.

这正是六亚甲基二胺遇到己二酸形成另一种品牌聚合物尼龙情况。

For example, it can respond to decreasing pHs by getting rid of one of the most common acid forming molecules—carbon dioxide— by well, breathing a little more.

例如，它可以依靠多呼吸方式摆脱最普通酸性形成分子，即二氧，而对酸碱值降低做出反应。

So this is ultimately what leads to certain kinds of amino acids forming certain kinds of structures and so on and so forth until you get the ladder of life.

这就是导致某些氨基酸形成特定结构等现象根本原因，如此循环往复，直至命之梯形成。
